Specification of Letters Patent.

Patented Aug. 29, fwilfi.

Application filed November 16, 1915. Serial No. 61,825.

To ail whom it may concern:

Be it known that I, VVALLAGE I. SrnursoN, a citizen of the United States, residing at Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Loom-Temples, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to loom temples and more particularly to the type of sectional roll temples wherein the cloth passes over a roll comprising rotatable gripping and nonrotatable smooth surfaced sections suitably mounted on the bolt or transverse axis of the temple. This type of temple is illustrated in the patents to I-Iarling No. 355,818 dated January 11, 1887 and Edward S. Stimpson No. 1,037,358 dated September 3, 1912.

In the weaving of certain classes of goods such, for example, as heavy corduroy or velvet where there is a considerable strain placed upon the goods by the temple and where any marks made by the temple teeth would show after the goods were finished and seriously injure if not destroy their marketability, it is necessary to hold the goods in the temple entirely by of the cloth. j

The object of the present invention is to provide a referred to which shall be adapted to hold goods under such conditions as referred to by the selvage in a satisfactory and efficient manner. This object is secured by providing essentially a pair of juxtaposed peripherally toothed roll sections mounted to 1'0- tate independently of and obliquely to the axis of the temple. By bringing the two toothed roll sections into juxtaposition the mimimum amount of space between the two rows of teeth is secured thus enabling the selvage to be gripped by at least two rows of teeth and by providing that the juxtag' posed roll sections shall rotate independently coincidence of movement between the teeth of each row in engagement with the selvage and the selvage itself is secured.

The object of the invention will appear more fully from the accompanying description and drawings and will be particularly pointed out in the claims.

In the drawings, Figure 1 is an inner side elevation of a 100m temple embodying the the selvage construction of temple of the type invention with the cap in cross section; Fig. 2 1s a rear end elevation of the temple, viewing Fig. 1 from the left, the cap being shown by full lines as raised, and in its normal operat ve position in dotted lines; Fig. 3 is a vertical sectional view taken on the transverse axis of the temple with the cap shown broken away; Fig. 4 is an inner end elevation of the left hand non-rotatable roll section shown in Figs. 2 and 3.

In the construction illustrated the shank 1 having the head 2 slidably mounted on the stand 8, the cap 4 pivotally connected with the head at 5, the cap locking stud 6, and the shoulder 7 on the head limiting movement of the cap toward the roll, may be and are p11 of usual construction in temples of this The sectional roll of the temple is made up of a plurality of smooth surfaced nonrotatable sections 8, 9, 10 and 11, and a plurality of rotatable cloth gripping or engaging sections 12, 13, 14C and 15. These sections are held together and the non-rotatable sections are mounted upon the bolt 16 extending transversely of the temple and at right angles to the head 2, and this bolt is held in place in the head by a suitable nut.

. The non-rotatable roll sections are preferably made of highly finished cast iron and the interposed rotatable cloth gripping sections are preferably made of brass or composition metal as usual in this type.

The entire roll formed by the two sets of non-rotatable and rotatable sections tapers away from the head and is so constructed that the upper surface engaged by the cloth is substantially continuous except for the cloth gripping surfaces of the rotatable sections and at the bottom the usual transverse groove extends through the non-rotatable sections to provide for the removal of lint and dirt.

Each of the series of non-rotatable sections 8, 9, 10 and 11 presents its side surfaces or faces obliquely to' the transverse axis of the temple and bolt 16, and each section is provided with a hub extending normally to and projecting from one of the side surfaces or faces so that each non-rotatable roll section with its hub is mounted obliquely to the axis of the temple or bolt, and the axes of these non-rotatable roll sections are all parallel to each other. At the end of t e temp e nea er the h ad the nontrated these sections '14 and rotatable roll sections 8 and 9 are arranged with their hubs 18 and 19 facing toward each other and so brought into juxtaposition with each other.

Each of the series of rotatable roll sections 12, 13, 14 and 15 are mounted respectively upon the corresponding hubs of the non-rotatable roll sections, and each of the rotatable roll sections is of frusto-conical shape to enable its peripheral surface atthe top of the temple roll to come into alinement with the general surface of the roll.

Those rotatable roll sections which come into direct engagement with the surface of the clot-h that is to be finished are not involved in the present invention and may be of any suitable character. As herein illus- 15 present one or more parallel grooves or recesses with corresponding edges or ridges. The strain on the cloth as it passes through the temple brings the cloth into engagement with these recesses, edges and ridges so that these sec tions act by engagement with the cloth to maintain the width of the cloth but withoutinjuring or damaging in any way the surface of the cloth.

The accurate and firm grip of the temple is obtained however, in this construction primarily by the toothed rotatable roll sections acting upon the selvage of the cloth. These toothed roll sections are illustratedat l2 and 13 and are also frusto-conical in shape. Each is toothed on its peripheral surface and preferably this toothed eonstruction is presented by a single circumferential row of radially projeetingteeth 20. These two rotatable roll sections 12 and 13 are mounted upon the juxtaposed hubs 18 and 19 of the non-rotatable sections 8 and 9, and thus the rotatable toothed sections 12 and 13 are brought into juxtaposition. This construction brings the two rotatable toothed sections 12 and 13 as close together as is possible and insures the minimum distance between the two rows of cloth gripping or engaging teeth 20. Thus the selvage is firmly gripped by two rows of teeth and held against the strain to which the goods is subject in the temple. Furthermore, by reason of the fact that these juxtaposed toothed roll sections are mounted for indeaxis of the bolt and mounted upon said bolt,

a hub projecting from said oblique face and normal thereto, a second non-rotatable roll sectlon mounted upon said bolt and having faces parallel to the oblique face of the first non-rotatable roll section, a. hub projecting normally from one of the faces of said second section into engagement with the hub of the first section, a pair of juxtaposed roll sections, each provided with circumferential radially projecting teeth, mounted respectively on said hubs to rotate independently and means for causing said bolt to clamp said non-rotatable sections together and against said head whereby relative rotatable movement of the non-rotatable sections is prevented and said rotatable roll sections are adapted to engage the cloth along closely adjacent lines at the selvage thereof. 2. A loom temple comprising a head, a bolt extending from said head, a non-rotatable roll section having one of its faces engaging said head and the other face oblique to the axis of said belt, a hub projecting from said face and normal thereto, a second non-rotatable roll section mounted on said bolt and having parallel faces oblique to the axis of the bolt, a hub projecting normally from one face thereof into engagement with the hub of the first non-rotatable roll section, means for causing said bolt to clamp said non-rotatable roll sections together and against said head and a pair of juxtaposed frusto-conical peripherally toothed roll sections mounted respectively on the said hubs to rotate independently.

In testimony whereof, I name to this specification.
